Enjoyed an excellent walk around the farmland between Crookston and Paisley doing a Timed Tetrad Visit for the bird atlas. Highlights included a Treecreeper (rarely seen hereabouts), two singing Yellowhammers (above), good-sized flocks of Swifts, four or five Whitethroat territories, Swallows and House Martins feeding at several locations, breeding evidence for Mallard, Magpie, Jackdaw, Woodpigeon, Blackbird, Swallow, Greenfinch, Chaffinch, Blue Tit and Great Tit, and two new birds for the tetrad and the whole area: Sand Martin and Reed Bunting. The walk back over the fields (below) was like stepping back in time, with the lanes full of finches and buntings.
